Abstract
In a large turbine generator unit having a liquid-cooled rotor, the liquid coolant is introduced into the rotor through the central bores of the exciter shaft and the generator shaft. This requires coolant tubes and electrical conductors for the field excitation current to be placed in the bores of the shafts, and requires joints between the coolant tubes and connections between the electrical conductors at the junction of the shafts in addition to a mechanical coupling for making a driving connection between the shafts. The invention provides means for making the necessary coolant tube joints and electrical connections within the mechanical coupling after the exciter and generator shafts have been aligned and are in the final coupling position.
